This is our first R markdown document. In this section we will do a quick introduction about Japanese culture followed by a video and a text to explain what we think about it. As you will see in the third section their will be a presentaion of what each person likes the most for example with Jetnisa it will be japanese culture and for Mehdi will be Arthur Conan Doyle and so on so forth. We will finish the assignement with R syntax and references that we used for our work.
Let’s take a look !
This is an introductory video about Japan itself and a bit of japanese culture. A presentation of common things in Japan followed by a background music. Of course there is much more to see in Japan but there is always a starting point !
The theme of my part will be on japanese culture, especially on one of my favorite movie which is “le Voyage de Chihiro” (aka “Spirited away” in english).

It’s a scene from the beginning of the movie before Chihiro’s parents misteriously disappeared. After that, she will do everything in her power to find them …
When Chihiro and her parents discovered this misterious village …

Misleading answers by using the cache option
(a <- 5)## [1] 5
we putted a being equal to some random uniform number
(d <- 0.5*log(2*pi*exp(1)*a^(2)))## [1] 3.028376
It should give the right answer
(d <- 0.5*log(2*pi*exp(1)*a^(2)))## [1] 3.028376
However when you change again the value of a there will be a mislaeanding answer since by the cache function R stores the old value of a. To fix this problem we need to add another comment on the chunk code which is dependson. This will tell the program to take the value of a and not the saved one. Cache can be very useful to save computational time.
Random sample
n = 100
x = rnorm(n) # Generates 100 random numbers and stored in a vector
(median(x))## [1] -0.02955193
(mean(x))## [1] -0.04126467
(var(x))## [1] 1.118109
It is normal to get values different from what expected as n is not big enough. As n grows we will get values close to the predicted ones. As we can see by changing the n = 100000 below
n = 100000
x = rnorm(n) # Generates 100000 random numbers and stored in a vector
(median(x))## [1] -0.009499153
(mean(x))## [1] -0.007793546
(var(x))## [1] 0.9971184
Histogram
b = 100
x = rnorm(b) # Generates 100 random numbers and stored in a vector
hist(x)Mathematical equation
\[E[var\{v_1(\hat \theta,n|\hat \theta)\}] = var\{v1(\theta_0,n\} + E[\vartheta_p\{D_1(\theta^*,n)(\hat \theta-\theta_0),...,D_p(\theta^*,n)(\theta-\theta_0)\}] = var\{v_1(\theta_0,n)\} + \vartheta(n^{-2})\]
In line equation
\[ A \equiv [a_{ij}]_{i,j=1,...,p} \]
